Who Sponsors Stuff

Who Sponsors Stuff answers a question every newsletter operator eventually asks: who is already spending money on newsletter ads in my niche?

It is not a marketplace like Paved and not a booking storefront like Passionfroot. It is sponsor intelligence — a living database of brands, contacts, creative examples, and competitive sets built specifically for email advertising.

What is Who Sponsors Stuff?

Who Sponsors Stuff (WSS) tracks hundreds of newsletters and thousands of sponsors to show which companies buy ads in email, where they advertise, and how their campaigns look. The paid Sales Pro product adds searchable data, CSV exports, saved searches, daily alerts, and unlimited team seats.

Morning Brew, The Future Party, 6AM City, and other established newsletter businesses use Sales Pro to keep a pulse on sponsor activity — which tells you the product is built for operators who take ad sales seriously.

Key features for 2026

1. Sponsor database with direct contacts

Sales Pro includes contact information for thousands of sponsors actively buying newsletter ads — the raw material for outbound pitches without guessing which brands might be interested.

2. Saved searches and daily alerts

Monitor new sponsors entering the newsletter channel. WSS reports roughly 20 new sponsors per day and 100 per week across the database.

3. Creative archives and competitive sets

See the actual ads, landing pages, and tracking patterns brands use. Track newsletters in your space and know which companies advertise where — up to the moment.

4. Free public research

Top-sponsor rankings, niche breakdowns (B2B, AI, investing, software, and more), and free tools like the newsletter ad calculator give you a taste before committing to Sales Pro.

Who Sponsors Stuff vs Paved vs Passionfroot

These tools stack rather than compete. Passionfroot gives you a storefront. Who Sponsors Stuff gives you a prospect list. Paved gives you inbound marketplace demand once you have scale.

Final verdict

Who Sponsors Stuff is the research layer I would add once you are ready to run proactive sponsor outreach — not when you are still hoping a marketplace saves you.

Sales Pro is a paid product with unpublished pricing, so treat it like a business expense that should return after one or two closed deals. Start with the free top-sponsor lists to see if the data quality matches your niche, then talk to their team if outbound sales is part of your monetisation plan.
